There is no neutral ground in the universe. Every square inch, every split second is claimed by God, and counterclaimed by Satan.” – C.S. Lewis

2024 Symposium

August 30 – 31, 2024
Providence Christian College

Life gets so busy with so many decisions and crucial choices.  What career should I choose?  What degree? Can I only please God as a pastor or missionary?  And, what about dating, marriage, and sexuality?  Then there’s politics, the arts, and entertainment. Who am I, and how am I to be? How do I think and live in today’s world?

Join truthXchange this August 29-31st in Pasadena, CA, at Providence Christian College, where we will explore, be equipped, and be challenged to take Christ’s lordship to the streets where everyday life is lived. At this event you will be changed for God’s glory and you will not view the world in the same way when you leave. EVERY square inch of creation is Christ’s; let’s live like it. And let’s do it together.

Dr. Peter Jones

I was born in Liverpool, England, where I would buy fish and chips on Penny Lane with John Lennon, a high school friend with whom I shared a desk for five years. Not that we did much at those desks! I was too interested in football (soccer), while John spent his time messing around. We played music together at school, but I never became a Beatle because my Christian parents wouldn’t allow me to go to clubs. When I got serious about my studies, I went to the University of Wales, then to Gordon Divinity School, near Boston. During my master’s year at Harvard Divinity School, I met Francis Schaeffer (through his books) and a Wellesley College student, Rebecca Clowney, daughter of Edmund P. Clowney, president for many years of Westminster Theological Seminary in Philadelphia.
